The taxonomic status of the Arizona myotis (Myotis occultus) is uncertain. Although the taxon was described as a distinct species and currently is regarded as such by some authors, others have noted what they interpreted as intergradation with the little brown bat (M. lucifugus carissima) near the Colorado-New Mexico state line. In this study, we used protein electrophoresis to compare bats of these nominal taxa. We examined 20 loci from 142 specimens referable to M. occultus and M. lucifugus from New Mexico, Colorado, and Wyoming. Nine of the 20 loci were polymorphic. Results show that there were high similarities among …

We assessed geographic and nongeographic variation among populations of the southern bog lemming (Synaptomys cooperi) in Arkansas, Iowa, Illinois, Kansas, Missouri, Nebraska, and South Dakota based on morphological data. Univariate and multivariate analyses of 15 cranial characters revealed no consistent sexual dimorphism. Geographic variation in cranial morphology of adults varied clinally, with individuals increasing in size from north to south and east to west. The largest individuals overall were from southwestern Kansas (S. c. paludis) and southwestern Nebraska (S. c. relictus), and the smallest individuals were from populations in eastern Illinois (S. c. gossii). We found only minor steps in …

The specimens on which this study is based were collected in litter under both the coast redwood, Sequoia sempervirens Endlicher, and Sierra redwood, S. gigantea Decaisne. The results of this study are the taxonomic discrimination of the speicies of each redwood region.
